I have been running a mythtv box for the last 12 months, first with 8.04 and then with 8.10. Once up and running the system has been running very reliably (except for an occasional x.org CPU 100% incident). When initially setting up the system I had some stability issues with my digital tuner - a Hauppauge Nova-T 500 Dual DVB-T. Those problems were that the tuners would disconnect by themselves and the programs would not be recorded. These issues were fixed by disabling EIT.
*However* last week I upgraded to 9.04 and the problems re-appeared. After a day or so of operation the tuners would fail - only a reboot would bring them back to life.

Fixes:
Some digging around shows that the driver for the Nova-T was updated in 2.6.28 and it also loads a later version of the firmware than previously used.
I reverted to the 2.6.27 kernel from 8.04 which loads the 1.10 version of the firmware and all is working well again. |
== work-around ==
Adding/setting the following options to /etc/modprobe.d/dvb-t.conf (from comment #7 and comment #12):
# Enable DiB0700 Low Noise Amps
options dvb-usb-dib0700 force_lna_activation=1
# Disable DVB remote(s)
options dvb-usb disable_rc_polling=1
